Hi,Kristy,"again". To cut the hole in the ceiling you will need a jig-saw. this you will want to buy,( It's a handy tool to have around,) for the other odd jobs, draw the square on the ceiling where you want the vent,drill two holes ,one at one side of the square and one on the other side (both holes bust be inside the square) then cut out with the jig-saw,. For cutting the hole on the outside wall, you can hire a small electric hammer, if you tell the guy at the hire store what you want it for he will show you what you want,"as him which is the best way to use it" he will give you some tips... Now:, first go up into the loft (above the ceiling where you want the vent pipe go to the out side wall, you will have a an idea of the size of the hole you want to cut. draw your hole (for the outside wall) from the inside.... drill four holes first (they must go through the wall, so you can see them on the out side. and then cut away the brick "important": cut half way on the inside, then go out side and cut out the rest, (this way you don't damage the bricks on the outside.. You should have no problems... But take care when you are up on a ladder... John 2000.
